given f(x)=4/x, fine the following values: a. f(3) b.f(4) c. f(-2) d. f(√2) e. f(2/x) f. f(3x)

Answer:
a.
[tex] \frac{4}{3} = 1 \frac{1}{3} [/tex]
b.
[tex] \frac{4}{4} = 1[/tex]
c.
[tex] \frac{4}{ - 2 } = - 2[/tex]
d.
[tex] \frac{4}{ \sqrt{2} } = 2 \sqrt{2} [/tex]
e.
[tex] \frac{4}{ \frac{2}{x} } = 2x[/tex]
f.
[tex] \frac{4}{3x} = \frac{4}{3x} [/tex]
